Abstract
ПЬЕЗОЭЛЕКТРИЧЕСКИЙ ВИБРАТОР, содержащий дискообразную кварцевую пластину, на торцах которой размещеныкольцевой выст-уп из моноокиси кремни и электроды в ее центральной части, отличающийс тем, что, с целью повышени стабильности частоты виходного сигнала, кольцевой выступ выполнен в виде четырех секторов, между противолежащими и параллельными кромками которых нанесено металлическое покрытие из материала с температурным коэффициентом линейг ного расширени (ТКЛР), близким к ТКПР кварцевой пластины, при этом металлическое покрытие размещено Симметрично относительно одной из главных кристаллографических осей кварцевой пластины.с $PIEZOELECTRIC VIBRATOR, containing a disk-shaped quartz plate, on the ends of which are placed a ring lid-up of silicon monoxide and electrodes in its central part, characterized in that, in order to increase the frequency stability of the running signal, the annular ledge is made in four sectors between opposite and parallel the edges of which have a metal coating of a material with a temperature coefficient of linear expansion (TCLE) close to the TKPR of a quartz plate, while the metal coating is is symmetrically positioned relative to one of the main crystallographic axes of the quartz plate.
